How You Spend Your 20s Will Define You

According to Meg Jay, Ph.D., a psychologist and author of The Defining Decade: Why your twenties matter--and how to make the most of them now, many 20-somethings believe they have all time in the world and how they spend their 20s doesn't matter. But Jay says they matter most. The foundation you build in your 20s will define the rest of your life. Take yourself seriously, she urges.
